Tibial shaft fractures in the adolescents: treatment outcomes and the risk factors for complications

Elastic Stable Intramedullary Nailing for Treatment of Pediatric Tibial Fractures: A 20-Year Single Center Experience of 132 Cases

Objective: The aim of this study was to analyze the outcomes and complications in children treated with elastic stable intramedullary nailing (ESIN) for tibial fractures. Methods: The study included 132 patients (92 males) with a median age of 11 years (IQR 10, 15) treated with ESIN for displaced tibial shaft fractures or dia-metaphyseal distal tibial fractures from March 2002 to March 2022. The median follow-up was 118.5 months (IQR 74.5, 170). The primary outcome was success rate, while secondary outcomes were the time of bone healing, length of hospital stay, and associated injuries. Demographic data, type and nature of fracture, indication for surgery, healing time, operative time, complications of treatment, and time to implant removal were recorded. Results: Complete radiographic healing was achieved at a median of 7 weeks (IQR 6, 9). Most of the patients (n = 111; 84.1%) had fractures localized in the shaft of the tibia. The most common injuries were acquired by road traffic accidents (n = 42) and by a fall in the same level (n = 29), followed by injuries from sport activities (n = 21) or motorbike accidents (n = 18). Associated injuries were reported in 37 (28%) children. Fractures were closed in the majority of the children (n = 100; 76%), while 32 (24%) children presented with an open fracture. Children with open fractures were significantly older than children with closed fractures (13.5 years (IQR 10, 15) vs. 11 years (IQR 8.5, 14.5); p = 0.031). Furthermore, children with open fractures had a significantly longer hospital stay (7 days (IQR 5, 9) vs. 3 days (IQR 3, 6); p = 0.001), a higher rate of associated injuries (n = 14 (43.7%) vs. n = 23 (23%); p = 0.022), and a higher rate of postoperative complications (n = 7 (21.9%) vs. n = 8 (8%); p = 0.031). No intraoperative complications were recorded. A total of 15 (11.4%) postoperative complications were recorded. Most complications (60%) were minor complications, mostly related to the wound at the nail insertion site and were managed conservatively. A total of six (4.5%) patients required reoperation due to angulation of the fragments (n = 5) or refracture (n = 1). Conclusion: ESIN is a minimally invasive bone surgery technique and is a highly effective treatment for pediatric tibial unstable fractures with a low rate of complications. Based on the given results, surgical stabilization of the tibial fractures using titanium intramedullary nailing can be safely performed without casting with early physiotherapy.
